A condensate pump. It's supposed to pump AC or humidifier waste water ... somewhere. Can't see if its hooked up right.

get a condensate pump and then you can send the condensate wherever you want.
You need to find a condensate pump. It's basically a small little pump contained in a little container. When the container fills up, it pumps it out. The pump is fairly small and doesn't draw much power.

yep, that's what these little pumps do:

I bought this ikea cabinet My plan is to cut a hole in the top with a 4in hole saw and put in a duct fan like this and run the duct out the window. The only problem is getting the printer out of the cabinet when the print is done but I figure it's easy enough to build a sliding platform for that.
Exactly. You can also run it into a little pump if there's no drain handy. For algae control, drop a treatment tablet in there.
The lights are one for 18 hours and off for 6. Mine come on at 4 PM and go off at 10 AM.
I'm just using a power strip with a built in timer. Like this. Half the outlets are on a timer, the other half are always on.
I used to keep my fans on the timer as well, but I recently swapped them out for quieter models that are less powerful/noisy. Now I just run the fans 24/7. My main fan has a thermostat in it and will slow down and speed up depending on the temperature in the tent. I find it convenient as I work from home and my tent is in my office. If I didn't sit in the same room as the tent all day, I'd probably just stick with a cheap duct fan like this. It's easy to overdo it with fans in a small tent. I originally bought a big 6" fan but it was overkill. My carbon filters died fast because I was pushing so much air through them and it made more noise than I could stand.
My setup is pretty simple and cheap, but it grows more than I can smoke and I don't have to spend much time worrying about it. I pretty much just did a little research, went on amazon found a grow tent, and bought all the 'people that buy this also buy...' stuff.

Well, I'm no HVAC expert, but here's an issue that keeps popping up for me because of my particular HVAC setup. This is a complete shot in the dark for you, because HVAC setups vary widely, but...
Do you have a condensate pump? Does it appear to be electrically wired to your furnace? Is the pump working? Is the drain line it's hooked up to blocked?
Some background: So, A/C units involve metal coils which sit in the middle of a furnace's airflow. These coils get cold, the furnace blows air over these cold coils so the air gets cold, then that now-cold air makes its way throughout the house through the ducts. Since the air being blown over the coils typically contains moisture, that water vapor hits the cold coils and condenses, forming water which then drips down into (hopefully) a pan. In some cases, the pan has a drain which leads outside. In my case, the furnace is in the basement, so the water drains into something called a condensate removal pump. This pump collects all the condensed water, then when the water level reaches a certain height inside the pump, it activates and with a buzzing sound pumps the water up through a flexible tube and out of the house.
Now, these condensate pumps contain a safety switch and are wired to the furnace by a couple of electrical leads. If the pump fails for whatever reason - it's not getting power, the motor is broken, the drain line is clogged, etc. - then the safety switch fails and the furnace consequently will not turn on. This happens to me on occasion, most often because the plastic tubing hooked up to the condensate pump gets clogged with sediment or algae or god knows what, and the pump therefore can't get rid of the condensation piling up inside it and trips the safety switch, thereby making the furnace unresponsive. In that case, unplug the drain tube from the pump, hook up a shop vac to the tube to suck out whatever's blocking it (I just use my hand to create a seal between the shop vac and the tube), then hook the drain tube back up to the pump. And for good measure, maybe pour a diluted bleach solution into the pump until the pump activates and flushes out the drain tube with the bleach solution. Assuming the pump is now running and draining fine, the furnace should now activate normally again.

Get a condensate pump and tie it into your dehumidifier. A condensate pump should be able to pump at least 25' vertically post discharge. Run that drain line either outside through the rim joist (with a final discharge at least 10 feet from the foundation) or run the discharge tubing up to your laundry tub/washer discharge drain.
Most humidifiers these days allow for a continuous drain so it shouldn't be too difficult to attach the condensate pump to it.
Edit: condensate pump
Run the AC condensate line to a condensate pump and then run the pump line outside or to a drain.
A portable A/C unit sound like your best option. Like the other post said, go for a dual hose unit if possible. These are more expensive but worth it. The single hose units will need to draw air from the outside albeit indirectly. I built a box around the lower coils of a single hose portable AC unit to draw air from the outside directly into the unit. The saved me from pulling air in from all over the house and running the building AC more.
As far as the unattended requirement, most portable AC units should have drain plugs. You can run a small hose from the upper and lower drains into a condensate pump. You then run a small hose from the pump out the window or to a nearby drain. The pump will gather the moisture into a small reservoir. Once the pump reservoir fills to a certain level, it will pump the water out the window or to the drain. Everything you need can be bought at most big box home improvement stores or amazon.

Whynter Elite ARC-122DS 12,000 BTU Dual Hose Portable AC https://www.amazon.com/dp/B01AA8WOAK/ref=cm_sw_r_cp_apa_i_x1pVDbBCRNERY
Tip: when buying the AC unit, make sure it has an upper and lower drain that have threaded or securable attachments. The Amazon link has a picture of the rear where you can see one between the hoses and one at the bottom. Take the screw caps off and then take them to the local plumbing home improvement store. Use the caps to find the proper size plastic connectors with a nib to connect tubing to.
Also, look at insulating the hoses to avoid unnecessary heat transfer. The hoses will get hot and are plastic so they will transfer the heat. Some simple pipe wrap can make a huge difference.
Screen the hoses from outside insects and critters. Keep in mind that even a screen can create back pressure. I dont like to screen right at the hose outlet. But if using the windows built inscreen, some air can be reflected into the intake, so a little blocking material can help the in and out flows.

Get this (or something similar, might be cheaper other places) and run it next to your space bucket. For one plant in a bucket this should be more then enough to keep smell out. Just set this up next to your bucket. Pull air through the filter and push it out the top of fan.
I bought a laser cutter and the stipulation was that I must have excellent fume control if I were to get one put in the warehouse. I didn't want to pay the crazy costs of a fume extractor. So, over the weekend I designed and cut this one instead. Here are all the parts necessary if anybody is interested in the costs. I chose very expensive filters - almost the most expensive I could find - and still came in way under the cost of a typical fume extractor:

So I'm ready to finish the assembly, but now I want to engrave something funny or cool on the door. Any good ideas?

I haven't heard of anyone doing that. I guess it could work, but how effective would it be? I can't say. If you wanted to experiment, maybe get some P100 filters and test it out on some alcohol or acetone fumes.
What I do to vent fumes, and I suspect what most people do, is to simply run a duct with a fan to a window. Any 4" or 6" inline duct fan will work well. They're easy to mount, they're cheap, and they're very powerful.
This 6" inline fan is the one that I use. I have it plugged into a speed control because I rarely need it's full 400 CFM sucking power. I usually use it at about half power. I mounted it under my workbench with the output duct permanently installed in an adjacent window. I keep the input duct retracted under the table so I can pull it out when I need it.
I don't have any fancy system for this. When I'm cleaning a part and I need to vent the fumes, I just pull out the duct from under the table and rest it on the workbench next to the cleaning vats (being careful not to suck up any paper towels or nitrile gloves... for the tenth time). It's a bit ghetto, but it's very effective. I usually can't smell anything when the fan is running. Even isopropyl alcohol fumes get sucked away faster than they can reach my nose.
Hope that helps.

Do you have power in your crawlspace? A light or something? Or possibly there's an outlet on the outside of your house? I had these guys http://www.eastcoastcrawlspace.com install the vapor barrier on the ground and up the piers and walls for $1200. I also bought this dehumidifier - https://www.amazon.com/Keystone-KSTAD50B-Portable-Dehumidifier-6-4-Pint/dp/B00IJYH02U that has continuous drain capabilities and this condensate pump - https://www.amazon.com/Little-554425-VCMA-20ULS-Condensate-Removal/dp/B000SM342Q/ref=sr_1_3?ie=UTF8&qid=1537466371&sr=8-3&keywords=little+giant+condensate+pump
I had an outside outlet circuit that was easily accessible from inside my crawlspace, so I just wired another outlet onto that circuit and mounted on the wall inside my crawlspace. I bought some hose from Home Depot to allow for continuous drain from the dehumidifier to the condensate pump and also some hose for the condensate pump and drilled a hole on the crawlspace doorframe to send the condensate drain hose outside. Once I had it all set up, it's just set it and let it do it's thing. I keep the humidity at 35 down there and never have a problem. You don't need a sump pump if you don't have standing water in your crawlspace.
A charcoal filter works for indoor use. I printed this adapter on my ender 3:

Thanks for the post. I have seen a few of these before, but this one motivated me to finally order everything. I have been wondering what I was going to do this summer. Currently my rigs costs me about $8.50 a day in electricity, but saves me about $5 a day since it is literally heating my entire house.
@ .12 kwh the fan at full speed costs $.55 a day. I ordered a bigger tent and 2 of the fans. Hopefully I can run them at some lower percentage (they come with controllers).
This is what I ordered:
If you aren’t planning on getting a bigger tent I would stick with a 4” exhaust and a 4”/6” carbon filter. Here’s the link for the fan and one for the filter . I use a bigger fan and filter personally, but that’s because I plan on getting a bigger tent after my third or fourth grow. Based on the dimensions of your tent this should be a solid setup for you even if you go up a bit in the future.

If you are only using butane torches and a pickle pot, you may be able to get away without one, but it is healthier if you use ventilation. You are going to inevitably burn oils and other contaminants and that should not be going into your lungs.
A 200 CFM, 4" duct fan can be used with a dryer hose and a 'vent periscope' box to make a permanent in-window vent system. Add some duct insulation and it won't bleed heat. The basic setup is about $60.

I'm using Acetylene, and that gives off soot, so I *need* a vent system. I will probably add a stove hood from the remodelling surplus store just for better smoke collection.
I don't smell my plants with my 4x4 closed. So the same thing should apply for you. Since you are venting outside you should be fine. It may be an light odor in the room. But it shouldn;t smell up the whole room until you open the tent.
This is the best on teh market. https://www.amazon.com/AC-Infinity-CLOUDLINE-S6-Controller/dp/B07FPFVZTZ/ref=sr_1_6?keywords=ac+infinity&qid=1554815892&s=gateway&sr=8-6 There one with a humidity control as well.

If your house has conditioned air, you might be able to draw off of that to cool your cabinet in the attic. A small cabinet can be cooled by a 4" line and a real exhaust fan. Install a bathroom fan style ceiling grate in an out of the way place (spare bedroom closet?) and no one will know what's up there. Just, uhh, don't pull from the bathroom... Not only would you suck bathroom smells into the tent, but if your bathroom fan is powerful enough and the door is shut, it could conceivably pull air from the tent into the bathroom 😬
Look for a fan that can do in the neighbourhood of 200cfm, preferably with a speed controller. I have this Vivosun one: https://www.amazon.ca/dp/B01DXYMGOM but if you're not on a budget, this one would be excellent: https://www.amazon.ca/gp/aw/d/B06ZXWN3BG
Avoid the super cheap "booster" fans, they're only useful as an add-on in the middle of a long run.
Can look into something like this
https://www.amazon.ca/Little-Giant-VCMA-15UL-horsepower-Condensate/dp/B000CCMUCM?source=googleshopping&locale=en-CA&tag=googcana-20&ref=pd_sl_9tbaio7us4_e
Route the tube to drain into the reservoir tank. When it fills it will pump water to where you hook it up to. Buses on high efficiency furnaces which have water come out like an AC does where there isn't a drain nearby.
I have a 2x2 tent and a Can Fan S-400, which was what my hydro shop recommended when I was getting started. There are no doubt cheaper 4" fans on Amazon, but it seems very well made and has a 5 year warranty. I also have a Vivosun 4" fan, which I run freestanding with an extra carbon filter attached to scrub the air during harvest. It works, and isn't especially noisy, but feels very cheaply made.
I've heard people say that a 6" fan turned way down can quietly move a lot of air, but haven't tried it, and a 6" fan on full speed could suck in the tent walls too much or even tear them. (I get pretty strong negative pressure with my 4" fan on full!)
I haven't used any fans with an integrated speed controller, but the external fan speed controllers that actually reduce voltage are vastly superior to the cheap ones that just rapidly flip power on and off -- depending on the fan motor type, the latter can damage the motor or produce loud buzzing as you slow it down past a certain point. When I tried one with mine, anything below 80% or so started buzzing. The better controllers cost a bit more ($70 vs. $15), but since it's actual industrial equipment it should have good resale value.
My tent is in my home office and I don't find the noise problematic, if that helps.
For a 2x2 tent, it's probably more effective to control humidity in the surrounding room, rather than putting a dehumidifier in the tent.
Disclaimer: I use propane, not coal. My advice is only based on other people's experience, not my own.
I think the problem is the idea that a hairdryer is going to pull the same weight a proper blower will. Companies are trying to save money by making products that meet, but just barely, their intended use. Use as a forge blower was never considered as a use-case when any hairdryer was designed. The duty cycle and run times aren't comparable and the operating environments are near opposites.
You see a lot of YouTube videos where people throw together a forge with this and that and it usually has a hairdryer blower. This might work for a bit or for the home gamer, but it can't last long term or fit the needs of a hobbyist or professional. You don't see follow-up videos or blog posts of forge owners praising their hairdryer blowers. You do hear when people upgrade and how much better it is.
I appreciate your pain. As a hobbyist myself, I've tried to make some tools that I really should have just purchased outright. Many times you can hack something great together that'll last a long time (i refused to spend two grand on a belt grinder, so I built one), sometimes it's better off to just get the right tool for the job (purchased the wheels for said grinder instead of trying to make them out of wood or skateboard wheels).
I think a proper variable speed fan for a forge blower is something I would just buy outright. Amazon even has a few cheap options you can put a speed control dial on. https://www.amazon.com/dp/B001OM1L7E/
How much money do you keep spending on replacing hairdryers until you get a tool that'll last forever?
Good luck

Unfortunately this is probably one of the more difficult things to get automated for relatively cheap and with enough confidence that it won't fail and cause water damage (low risk but high damage potential, so I would want something very robust)
If you use one pump and split it to the trays, once the first tray goes dry the pump won't pull from the others. And depending on the pump, you risk the pump not priming properly after it runs dry, so it might not pull anything.
Easiest would be to gravity drain each tray into a common bucket and empty that either manually or on a pump on a timer that drains it at some frequency.
I just found this condensate removal pump which might be a good fit, especially if you don't have a ton of waste water all at once.
I've never used that pump or one like it before, so no guarantees, but it actually seems perfect for this! I might get one and try it out myself sometime. I don't know how robust the moisture sensors are, especially with all the stuff in runoff water.
You could do a space bucket style build if you are lacking space and dont mind some DIY.
But if you want a tent style this is kind of like mine

will clear your humidity out in a minute or two. get a cheaper humidistat if you want, just needs to turn on and off at a set point, but the inkbird is a good value.
I used this one:

Along with a 3d printed duct for the back at the machine, with the blower positioned at the end of the hose. Works great.
I have a duct fan blowing into a carbon filter. It does a great job keeping the smell down.
How about a condensate drain pump for the air conditioner? Some systems need these to get rid of the water that your air conditioner pulls from the air. It would be beside the inside part of your air conditioner and would look something like this:

Hello there, I recently started growing and purchased all new items. The fan you chose simply won't work. You will be very disappointed in the performance. I was going to use that fan as an inflow booster with a pre-filter. I quickly returned it because it just did not move enough air. The fan could not create positive pressure in the tent. I then tried this fan: https://www.amazon.com/gp/aw/d/B01M7S46YZ/ref=mp_s_a_1_3?ie=UTF8&qid=1495901534&sr=8-3&pi=AC_SX236_SY340_FMwebp_QL65&keywords=4+inch+inline+fan&dpPl=1&dpID=41G0I96VBVL&ref=plSrch
I ended up returning that one as well because it was advertised as 200cfm and it was not moving anywhere near the same air amount as the first fan I bought. I then broke down and bought the same fan I originally purchased as my outflow fan and filter. I bought just the fan for 56.00 as an inflow fan and put a pre-filter on it.

bought this with some duct and a carbon filter
I put in multiple inline duct fans to even out the flow in one of my vacation rentals. Built in 1949 and the central AC system was added in 2007. It was poorly done and two different HVAC companies failed to get it anywhere near balanced, because like yours, this one has a sunroom that was added (converted from a deck). No room for insulation in the ceiling and the walls were 80% windows. I added a duct fan in that room and one in the nearby kitchen and they made all the difference in the world.
I used this one: https://www.amazon.com/gp/product/B01DXYMJ94 - it's great. Variable speed, can't hear it unless you're in the attic.
Using a vivosun 195 https://www.amazon.ca/VIVOSUN-Inch-Inline-Ventilation-Blower/dp/B01M7S46YZ got mine on fleabay. It's ok, I don't know if its bearings or bushings, its quiet ish. Cheap as fuck, the casing has no seal so it leaks, I fixed by using metal duct tape on the joint. 195 cfm is the unrestricted flow from the outlet. So after resistance of the ducting its reduced. Also the resistance of the filter (has to push or pull through) it drops even more. I'm 2x3 x 6.5, on hot days I dont get the airflow so I had to put in a second extract. I expect colder weather will be perfect for it in my particular circumstances.

https://www.amazon.com/dp/B071KXHCK3
pot growers run these for years at a time... literally non stop 24/7 for years.
if you need to duct any of it, you can use dryer hose for the outlet, but get something more rigid for the intake so it doesnt collapse.
So really this should do the trick?

Thanks for the reply brother. I did the same thing but I had this running on the bottom part of the tent.
Thought about doing the same thing that u did but my filter/fan in the tent is set up at the top. I was thinking that the air coming in will just get sucked up by my tent filter. I'll definitely give it a try tho, really want to try photos.
Where to start with my update.
I began collecting the parts for the controller. I am using a BME280 for the temp and humidity sensor, this little screen for reading conditions at the chamber, 8 channel relay to control the various electronics, this fan and this filter for fresh air.
Here is an album of updated photos. The first is a blast gate controlled by a servo to control the fresh air flow. When the fan turns on the servo will open the gate and allow the fan to suck air out (more on that later). Next up is the freezer with the collar on. Its not put together properly yet but just a rough test fit shows its looking good. Then I have two inside shots of the chamber itself.
After talking with someone who understands air flow much better than I do, I changed the position of fan and filter as well as direction. The fan is going to suck air out from one side and the other will have the filter on it. This will keep the lid down, where as if the fan pumped air in it could lead to a pressure build up and the lid may crack open slightly. The elbows are put in so its not just the top air that is circulating. I am thinking of turning them so they don't point straight down but for now its good.
The inside shot show the slots made to hold up to 7 bars. I am going to seal in the collar with a piece of wood on the top then fill it with spray foam insulation and silicone it to the freezer.
The other thing that has changed since I last posted was that I was going to try to do the code myself. As I got parts in and tried to put something together it became clear there is no way I can do it. After searching around I put out a bid on upwork.com and now I am working with a friendly fellow from Nepal. We haven't gotten to far but I am excited by his proposal and he will be adding the ability for me to control it from a webpage.
Anyway that is it for now. I can see there isn't much activity on this post or another related post but I am going to follow through with the updates because in my searches for this project I cam across a lot of half finished ideas and projects. RemindMe! 2 months
Get a grow tent , an inline fan and 8-inch flexible ducting . Put the fan in the uppermost part of the tent so it evacuates hot air, then stick the ducting so it blows out the window. Problem solved!
Sorry it should be inline fan
Here is one

Here is a pic of my setup
The filter and in line Fan I use together cost about $100. To connect it I 3d printed this part and super glued it to the back vent and put some sealer on. You could just buy a connecter tho.
Altogether about $600
$450 for the printer
$100 for the filter
And those minis only cost $20-30 in resin to print.I’ve printed other stuff som I’m not exactly sure.
And a bulk IPA pack for $20
This isn’t necessary but I also got an Ultrasonic cleaner for cleaning the prints when they are done.

Wanted to ask which fan you recommend. I was going to go with one of these: https://www.amazon.com/gp/product/B01M2XG0E1/ref=ox_sc_act_title_1?smid=A3I2VACYSJR5AQ&psc=1
Maybe even the 8" and turn the speed down if needed.
This paired with the bofa (while expensive) might give me the sound levels that would let me run this for a lot longer than just a few minutes at a time.
Thanks
Look into "self-leveling compound" to fix an uneven concrete floor.
I would assume you dont want to make the floor 100% flat, since there is a drain there. If you can level out any bumps & ripples, ceramic tile would be fine for a floor with a gentle downslope. Tile is used in the floor of showers all the time
Example of a [condensate pump](Little Giant 554425 VCMA-20ULS Condensate Removal 1/30 HP Pump with Safety Switch https://www.amazon.com/dp/B000SM342Q/ref=cm_sw_r_cp_apa_v.2IBbME5NADG). I don't know where you're located or local plumbing codes there. But you could look into it draining into a sump pump pit? Or doing a little bit of plumbing work so it can drain into a sewer line? We know sewer line must be accessible in basement because the washer drain goes somewhere.
if you do that, you will end up with a huge puddle in the morning.
​
But yes, you need a way for the water to come out. you can have it drain to a bath tub or something, or you could invest in one of these:
https://www.amazon.com/Little-554421-VCMA-20UL-115-volt-Condensate/dp/B000OLCGT8
​
it's a "condensate pump", you put the hose from your AC into it, and it will pump somewhere else to drain, like a kitchen sink or out that window.
This would be a condensate pump, and you could hook up a garden hose from your dehumidifier to this pump, and then use some vinyl tubing to bring that out to a utility sink or some other drain– that's how I have mine set up at least.
I purchased one of these to prepare for summer temps. It's stupid quiet, has good CFM, and more importantly good static pressure for sucking through ducting.

I have a piece of wood that's going in a window with this mounted to it connected to 6" flex ducting sucking air out of the back of a 24U enclosure.

I'm currently using their inline fan (VIVOSUN 4 Inch 190 CFM Inline Duct Fan with Variable Speed Controller for Ventilation https://www.amazon.ca/dp/B01DXYMGOM/ref=cm_sw_r_cp_apa_i_5ihjDb9NQHYHD)
Anyone know if this is something I should replace too? Still under return period.
Yes, there’s a blower like this one https://www.amazon.com/dp/B07HFQTJH9/?coliid=I28Q2FG7UOZXSO&colid=HLB6M8WGEQCM&psc=0&ref_=lv_ov_lig_dp_it to pull through carbon granulates.
More research points to this being pretty quiet
https://www.amazon.com/PSI-Woodworking-DC3XX-Portable-Collector/dp/B01CU7DKTI#aw-udpv3-customer-reviews_feature_div
But that perhaps the laser would be louder than the fan anyway? Or that I could build a wooden enclosure to lower the noise? And buy a 6 inch hvac of 240 cfm?
And maybe this would be quiet and powerful enough:

It's not the zone controller that is the issue, it is Nest (and most other WiFi thermostats) need a C.
Options:
I wouldn't sleep while it's running. But the one you linked won't ship to me.
But i found a similarly powered exhaust fan.
This one
I've already found tubing and a filter to use.
As for noise I also have a FDM printer in my room that I run occasionally, so I'm sort of conditioned to it.
Set up was super easy, old port screws right off and you screw the new one right one and then slap on a filter and a fan (any carbon filter should do but here’s what I bought that works well)

This really works well for me. The smell otherwise is intolerable. Carbon filters are really amazing.
I don't have that much vertical space either...
What I did last time was cut a 1" hole to the bottom of root container, added a fitting for a short hose that ran into a condensate pump.

You'd have to buy a power cord and wire it in (simple wire nuts). I've got it clamped to a 2" pipe flange. 50 cfm is plenty, and you don't need a rheostat to adjust flow, you just swing the air gate over the eye of the impeller. I usually run it about 1/8 to 1/4 open and get plenty of flow, but I have a relatively small firebowl.
This is a pretty sweet little fan and it's very quiet. I also bought a stomp switch that plugs into the power cord. You can just wire in a simple switch instead.
It's got a very low current draw as it has a solid state rectifier that converts the single phase standard AC to three phase. That's one of the reason I didn't use the rheostat because I didn't want to mess with the circuit. It's a 0.26 amp draw, so if you want to use it freestanding, a relatively cheap converter and battery could make it work, but that's getting pricier. I'm going to mess with a thermoelectric generator and see if I can power the fan off the forge heat.
Power cords run about $10 or less. That fan is $60.
PSA to anyone running a dehumidifier: Buy one of these and never empty another bucket. You don't need that specific model but it should give you the idea. Mine pumps the water like 50ft away into the same drain I use for my washing machine.
It’s possible because there is no airflow, also it will cool your tent down. I bought 2 fans and some 4” ducting from amazon and probably paid about $50.

I have one size down for my 40w epilog and would like a bit more flow. Of course my run is not efficient so I will see how I feel after fixing that.
You can never have too much exhaust flow IMO
So I made this thread recently about a clone I bought on 4/20/19.
​
Now, a bit of time has passed and it's grown a bit more, but unfortunately still under very inadequate lighting. The temp and humidity were wrong this entire time, but I seem to have stabilized that. I plan on ordering this grow tent, just ordered this LED light, and am looking at this (or this) in combination with this to bring it all together. Anyone see any reason why this wouldn't be enough?
How many of your side vents are open? Do you have any fans inside your tent moving air around? I have a 4 in PVC pipe that is inserted into one of the 4 inch opening in my 3x3, to allow unrestricted air into my tent.
For 25 dollars, you could buy one of these, and have it pull fresh air in.

Expanding on /u/org4nics said, a split system would be good.
A split system is like a central AC unit, it has an outdoor part and an indoor part, but no ducts. You mount the indoor part in the room to cool, connect your pre-manufactured and charged lies, and then hook up your out door part.
Add a drain line to the indoor part, or the basic condensate pump and you have a serious cooling system!

That is a condensate pump. It's got some power to it so it will send the water wherever you want it to go. Get a long piece of tubing and route it from the condensate pump to wherever a good drain is. The same drain your washing machine or dishwasher uses could be an option. Either way, a proper condensate pump is your best solution. Trust me, a good condensate pump is worth the 50 bucks.
